ATFD stands for evaporation of water solvents to make the concentrated liquid to dry powder or flakes. Based on application either recovered solvent or dry product is important. Agitated Thin Film Dryer is the ideal apparatus for continuous processing of concentrated material for drying. Agitated Thin Film Dryer is consist of cylindrical, vertical body with heating jacket and a rotor inside of the shell which is equipped with rows of pendulum blades all over the length of the dryer.The hinged blades spread the wet feed product in a thin film over the heated surface. A highly agitated bow wave is formed in front of the rotor blades. The turbulence increases as the product pass through the clearance before entering a calming zone situated behind the blades. As the heat will transfer from jacket to the main shell under the smooth agitation water/solvent will evaporate and liquid will convert to the slurry, to cake and to dry powder or flakes.He vapors produced rise upwards, counter-current to the liquid and passes through a Cyclone Separator mounted at the vapor outlet of Agitated Thin Film Dryer(ATFD). Further, these vapors will be condensed in a condenser and recovered as condensate.The system will be operated under vacuum for temperature sensitive products and atmospheric conditions for normal drying.

Applications:Agitated thin film Dryer is used to recover complete water contain from the concentrate outlet of MEE.
